Okay so it does seem that this may be an issue with the app version, so do you mind doing me a favor and sending a support request through the Wyze app so that the Wyze developers can take a look into this further?

Instructions on sending in support request
Open Wyze app > click “account” > then “help and feedback” > and press “report an issue”. Make sure that you include “Log files”.

I found a problem with my pan cam yesterday .
When I tap voice It turns on the mic And the sound , every time I tap voice to stop speaking it turns off the sound Also .
If I tap sound to on, it will stay on but If I turn the mic on then off Sound gets turned off again
